Gruppe B ? Streptokokken im Genitale der Frau

Abstract

Swabs taken from the vagina, cervix and urethra of 152 women without any clinical signs of infection were studied for the presence of group B streptococci. 36.8% of these women were found to have group B streptococci in their genital tract. Isolation of streptococci took place by way of enrichment and selective culturing, determination of biochemical criteria as well as serological grouping and typing. Streptococci of human or animal origin which may be identified by precipitating group B antiserum were found to be identical. There were no criteria for a differentiation between human and animal (bovine) group B strains. Epidemiological associations between human infections and the consumption of raw milk containing galt streptococci have never been confirmed. Group B streptococci are present indepently in animals and humans. In humans, they may be present as saprophytes in the throat and female genitals and also cause severe disease like endocarditis and meningitis. There is no proof of the etiologic role as an agent of zooanthroponoses.

Die geburtshilflichen Infektionen

“…Eine Keimart, über die in letzter Zeit sehr viel geschrieben wurde, sind B-Streptokokken (2, 10,12,17,20). Die Trägerquote während der Schwanger schaft liegt zwischen 5 und 36 %.…”

Immunopathological investigations during the course of arthritis induced in rats by Streptococcus agalactiae

“…Streptococcus agalactiae is a pathogenic bacterium in man and animals. It is located in the urogenital tract of 36.8 % of women (Obiger 1975). Triscott (1983) isolated S. agalactiae from arthritic patients.…”

Diagnostical availability of the hemolytically active exosubstance of Corynebacterium pseudotuberculosis for isolation and identification of Streptococcus agalactiae and its comparison with the beta-toxin of Staphylococcus aureus

“…

The classical way of identifying Streptococcus agalactiae, known as CAMP-test (2), is based on interaction of its hemolytically active exosubstance with staphylococcal beta-toxin (4).The most usual technique consists in testing streptococcal strains against a beta-toxin producing strain of Staphylococcus aureus on blood agar with ovine or bovine erythrocytes (2, 4, 5, 9, 10, 13, 17, 24, 25,26,31). Some authors replaced the Staphylococcus aureus strain by isolated staphylococcal beta-toxin (23,37).The isolated, and to a different extent purified, staphylococcal betatoxin together with ovine or bovine red blood cells is of avail for direct diagnosis in the substrate (18,19,29,36).
